-nAnn n. HAMILTON, or' PEKIN, INDIANA. TUBE HOLDIG AND COHPRESSING MEANS.

rlginal apptlicstion med April 2, 1925, Serial No. 20,218. Divided ,and this application led'August To. all iolwm z't may concern:

Be it known that I, EARL R. HAMiLToN, a citizen of the United States, lresiding at Pekin, in the county of Washington and Y State of Indiana, have invented certain new 'l and useful Improvements in Tube Holding and Compressing Means; and I do declare the following to be a Jiiull, clear, and exact i description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This application relates to -improyements in means for holding and compressing collapsible tubes, such as those in which v arious kinds of pastes are marketed, and the invention is intendedprimarily for use in connection with an applicator to which the contents of the tube are delivered when said tube is compressed or collapsed. The applicator construction while illustrated herein in a general way, 1s claimed in my parent U. S. application Serial Number 20,213, filed April 2, 1925 and the present application forms a division ot said parent case.

@ne object of the invention is to provide' a new and improved form o-holder for a collapsible tube, so constructed that it may readily be carried from lace to place or compactly stored without anger of leakage, provision being made whereby an empty tube may readily be removed and a new tube substituted therefor.

Another object is toprovide an exce tionally simple and inexpensive, yet an e `cient and reliable means for compressing the tube to discharge its contents. n c

With the foregoing in view, the invention Aresides in the novel subject matter herein- -vided at its upper end with a permanent stationary closure 2, while a removable closure 3 is provided for its lower end. This removable closure is preferably stamped 6, 1925. Serial No. 48,587.

from sheet metal, in substantially the form of a cup, and the upper or inner portion of the continuous side wall 4, of-said closure, is receivable removably in the lower end ot the casing 1, any desired quick detachable connection being provided between the two. Preferably, the wall 4 is formed with headed studs 5 and bayonet slots 6 areA provided in the casing wall to engage said studs. Between' its upperand lower ends, the wall d is provided with an outwardly stamped, eX- ternally serrated ortion constituting a rib which may rea ily be gripped when the closure 3 is to be either removed or applied. When in operative position, this rib of the closure 3, abuts the lower end of the tubular casing 1.

In the construction shown, the bottom portion of the closure 3 is formed'with an opening and with an annular depending flange 8 around the same. Within this flange, the

lupper end of a tubular discharge neck 9 is secured in any desired manner, the upper end if said neck being internally threaded as at 10 for engagement with the usual discharge neck 11 of a compressible tube 12 receivable inthe casing 1. The lower end of the neck 9 is here shown as provided with an applicator 13 whose construction is full vdescribed and claimed in the parent application above referred to. The part designated at 14, is merely a pin normally closing the neck, which pin is withdrawn when it is desired to discharge some of the contents from thetube 12.

I have provided novel means for compressing the tube 12 to discharge its contents.- 27 designates a ram located in the casing 1 and adapted to engage the, upper end of the above mentioned tube. is ram may well be in the form of a flat plate and it is carried by the lower end of a bar 28 disposed longitudinally in the casing, the upper end of said bar being preferably, though not necessarily bent into C-shape as indicated at 29, the arms of the C, and ram 27, being formed with alined openings 30. A nut 31 is non-rotatably held between the above-named arms of the C-shape formation 29, and a longitudinal screw 32 is threaded through this nut, said screw passing slidably through the openings 30. `T e upper end of the screw is swiveled as at 33 in the closed end 2 of the casing 1, and is provided with an appropriate operating handle 34 by means of which the screw may readily be rotated. Obvious- Siti ly, by turning this handle -in the roper direction, the ram 27 will be forced ownwardly, thus compressing the tube 12 for the purpose of. discharging its contents to the applicator head, in desired 'quantities To normally cover the applicator head and associated parts, thus eiectively protecting them against dust and the like and also preventin soilin of articles by coming in contact ywit said ead, I have provided a cap to enclose these parts. This cap lits rictionally over the lower end portion ot the annular side wall 4, of the closure 3 and abuts the lower side of the rib 7. When inserting a new tube into the casing 1 or removing an old one, the closure 3 is entirely detached from said casing 1 and may at that time carry with it the cap 35. Then, the screw threads 10 are readily accessible so that the new tube may readily be inserted after the removal of one whose contents have been discharged.

As excellent results are obtainable from the details disclosed they are preferabl tollowed. However, within the Scope of t e invention as claimed, modications maybe made.

I claim:y

1. A device of the class described compris- ,ing a tubular casing, a ram therein, a longitudinal bar in the casing carrying said ram at one of its ends andhaving its other end bent to form a C-shaped socket, the arms of the socket and said ram having alined openings, a nut held in said socket, and a screw swiveled in said casing and passing slidably through the aforesaid openings and threaded through said nut.

2. A. device of the class described comprising a tubular casing, a ram therein -having an opening near one edge, a longitudinal bar in the casinoi fixed at one end to the ram and having its other end bent laterally, the laterally bentl portion having an opening alined with the opening in the ram, a nut carried and supported by and l secured against axial movement independently of and by said laterally bent portion, and a screw swiveled in said casing and passin slidably through the aforesaid openings and threaded through Said nut.

`ln testimony whereof I have hereunto affixed my signature.

EARL R. HAMLTON.
